I have requested assistance in cleaning up the LESS library and style file referenced in the head section of the application to reduce redundancy and improve load time. Currently, the style.less file is being used as the main stylesheet, importing other less files such as variables, mixins, base, kendo, header, navigation, lists, and treeview. The goal is to consolidate all these into a single CSS file named style.css. While most of the files are compiling correctly, issues persist with variables.less and mixins.less not converting to CSS. It seems that nested rules within these files might be causing errors. I've heard that a config file may be necessary to properly process nested variables and mixins when using plain CSS. Any guidance or solutions you can offer would be greatly appreciated. Thank you.
